European Commission's Top Scientific Body Concludes That
Honeywell's Low-Global-Warming Refrigerant Is Safe For Use In
Automobiles

MORRIS TOWNSHIP, NJ--March 7, 2014: Honeywell announced today that
the European Commission's top scientific and technical body has concluded
that Honeywell's new low-global-warming-potential mobile air conditioning
refrigerant, HFO-1234yf, is safe for use in automobiles, marking the final
word in a thorough and inclusive evaluation process.

"A scientific review of the research regarding the safety aspects of the
use of refrigerant R1234yf in Mobile Air Conditioning (MAC) systems,
published today by the European Commission, concludes that there is no
evidence of a serious risk in the use of this refrigerant in MAC systems
under normal and foreseeable conditions of use," the European Commission
said in statement today (European Commission)
following an extensive evaluation by the Commission's Joint Research Centre
(JRC). "The review reinforces the conclusions by the German market
surveillance authorities, the KBA (Kraftfahrt Bundesamt), which stated that
there is no sufficient supporting evidence of a serious risk that would
entail the intervention of the authorities."

JRC today issued a 17-page report (Automotive Environment)
supporting its conclusions after a three-month evaluation during which it
thoroughly reviewed the extensive testing done by a range of leading
automakers as well as the world's foremost automotive engineering body, SAE
International, and independent test agencies.

The JRC provides independent scientific and technical advice to the
European Commission to broadly support policy-setting activities. It
oversees seven scientific institutes across Europe with a wide range of
laboratories and research capabilities.

"The JRC's independent and unimpeachable report leaves no doubt that
HFO-1234yf is safe for automotive applications," said Ken Gayer, vice
president and general manager for Honeywell Fluorine Products. "We continue
to see strong adoption by global automakers of this new refrigerant as they
work to meet new environmental regulation, especially in Europe, and are
investing in production capacity to ensure adequate supply."

HFO-1234yf, a highly efficient, safe and effective replacement for the
current automotive air conditioning refrigerant, HFC-134a, is already
widely used by the auto industry. There are more than 500,000 automobiles
safely using HFO-1234yf on the road today, and by the end of 2014 that
number is expected to grow to more than 2 million. Third-party data shows
that HFO-1234yf's widespread adoption globally would have the greenhouse
gas equivalent of permanently removing more than 30 million cars from the
road worldwide, or about 3 percent of the total global fleet.

HFO-1234yf is being adopted by automakers in part to meet the European
Union's Mobile Air Conditioning (MAC) Directive, which aims to reduce the
greenhouse gas emissions of air-conditioning systems in passenger cars and
light commercial vehicles. As reconfirmed last month by the
Intergovernmental Panel on Climate Change (IPCC), HFO-1234yf has a global
warming potential of less than 1, which is even lower than that of carbon
dioxide. This GWP is 99.9 percent lower than that of HFC-134a with a GWP of
1,300, which makes it an especially potent greenhouse gas. The JRC began
its extensive evaluation of the extensive testing already conducted on
HFO-1234yf in October 2013 at the request of The Directorate General for
Enterprise to conclusively determine the safety of the refrigerant.

Daimler in late 2012 had raised questions about the refrigerant's safety
due to its mild flammability. Last year, SAE International, the world's
leading automotive engineering organization, which comprises engineers from
the world's leading automotive manufacturers, concluded that the
refrigerant was safe after completing an expanded and extensive evaluation.
Those conclusions were backed by 10 global automakers who took part in the
SAE Cooperative Research Project, including Chrysler/Fiat, Ford, General
Motors, Honda, Hyundai, Jaguar Land Rover, Mazda, PSA, Renault and Toyota.
The SAE report called Daimler's testing of the product to be
"unrealistic."

SAE representatives as well as experts from several global car
manufacturers also presented at JRC meetings, and the JRC reviewed testing
and evaluations from multiple SAE Cooperative Research Programs as well as
more recent testing by the KBA. The KBA's testing demonstrated that using
HFO-1234yf creates no serious risks, and as a result it did not pursue
action under Germany's Product Safety Act.

SAE International, formerly known as the Society of Automotive
Engineers, is an independent, global association of more than 133,000
engineers and related technical experts in the aerospace, automotive and
commercial vehicle industries.
